Research on finite element analysis and lightweight design for the rear frame of BGC-60D slag pot carrier

采用轻量化设计理念和计算机模拟仿真,在SolidWorks中建立了BGC-60D抱罐车后车架结构模型。利用有限元法对满载起包和满载运行工况下的后车架结构进行了应力应变分析并对关键构件的应力强度和安全系数进行了分析。基于最优化理论在ANSYS有限元分析软件中优化模型。通过研究分析确定了后车架结构的应力分布和变形情况,以重要构件的材料厚度为优化变量对后车架进行轻量化设计,优化后的后车架结构质量较优化前减轻了6.64%,达到了轻量化的目的,为抱罐车的结构设计和轻量化提供了理论指导和实际应用参考。

Lightweight design concept and computer simulation analysis method are taken as the research means in this project.The three-dimensional solid models of rear frame of BGC-60D slag pot carrier are established by the SolidWorks software,and the finite element models of rear frame is optimized with ANSYS.In both cases of holding and transporting slag pot,the rear frame is processed by using finite element method for stress-strain analysis.The stress intensity and safely factor of key components are analyzed for improving the structural property and achieve the purpose of lightweight.Based on the optimization theory,the command stream of rear frame is established by using ANSYS parametric design language.The monolithic construction of rear frame is reduced by 6.64%,and the objective of light weight is achieved,which provides the important theoretical and practical reference for structural design and lightweight design of slag pot carrier.
